SPECIFICATION forming part of Letters Patent N 0. 787,429, dated April 18, 1905. Application filed December 9,1904. Serial No. 236,114.

To all whom it may concern.-

Be it known that I, WILLIAM J. BODA, aciti- Zen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Nails and Methods of Concealing Same in Interior Finish and Fancy WVoodwork; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to a new and useful sion closed bymeans of the side in Fig. 5 and the application method for unitinginterior finish in buildings 1 and other fine woodworksuch,

for example, as buggy-work, cabinet-work,

mantels, &c.

and all kinds of woodwork Where the surface is finished either in oil, varnish, or paint.

The object of the invention is to provide means for uniting said parts and whereby the nails driven through the woodwork from the exposed surface will not leave any indication or sign in the surface of the wood of their entrance. In other words, the fibers or grain of the wood is enabled to close the wound or incision in the wood, so that the head of the nail after the latter has been countersunk in the wood is invisible, and the use of putty in closing the wound or incision is avoided.

The nail is preferably oval or oblong in cross-section, so that it acts as a wedge, and is driven into the wood with its greatest crosssectional width lying parallel with the fibers or grain of the wood. The fibers or grain of the wood are thus separated at the point where the nail enters.

Preceding a detail description of the invention reference is made to the accompanying drawings, of wl1ich- Figure 1 is a perspective view of a block of wood, showing an incision being made therein for the initial entrance of the nail by means of a chisel. Fig. 2 is a sectional view showing the edge of the chisel and the extent or depth of the incision; Fig. 3 is a perspective view showing the nail being the incision. F

driven through ig. 4 is a similar view showing the completion of the driving of the nail I and the same countersunk, leaving the wound or incision in the Fig. 5 is a similar or incision as nearly closed sions upon which is placed. Figs forms of chisel for making the nail incision and the side incisions in the wood. Fig. 8 is a perspective view of the block as it appears after the nail has been driven and the inciincisions shown of moisture or liquid compound.

In a detail desc ription of the invention similar reference characters indicate corresponding parts.

is employed to In carrying out the method I ing a cross-sectional shape similar to the nail,

a chisel 1, havmake the initial incision 2,

which is preferably about one-eighth of an inch of the nail-head. This The and countersunk by sions 4 on each si de of the nail incision. The

point of this chisel tapers on'one side in order that the outer side of the incisions 4 will be straight, while the inner side of said incisions will slant in the d These incisions 4 cient to enable the fi hers contract or come nail-that is to sa extend down to a of the nail; but

depth to enable the head of the nail incision. In the use the side incislons 4 natural tendency irection of the nail incision 2. need be only of a depth suffior grain of the wood to together over the head of the y, the side incisions 4 need not point on a level with the head they should be of sufiicient fibers to contract above the completely close the nail of the smaller sizes of nails may be dispensed with. The of the fibers or grain of the wood is to contract or come together, and

this natural tend ency is aided by applying to the incisions moisture in the form of water l or in the case of oak or cherry a liquid compound composed of water, whiting, and pigments of colors suitable to the wood. The chief requisite of this compound is its moisture, and the same is applied to the incisions by means of asmall sponge holding but a few drops, which when entering the incisions has the effect of accelerating the tendency of the fibers or grain of the wood to come together, and thus close the incisions,thereby leaving the surface of the wood as if no nail had been driven therein. It may be further stated that the liquid compound in addition to its action as above indicated neutralizes the effect of the acid in the wood when the liquid or moisture comes in contact with the nail, thus leaving a nice, clean, and bright joint where the incision has been made and the nail passed through; otherwise the action of the acid which is inherent in the wood coming in contact with the metallic nail would leave a black streak in the wood at the point of incision. The chisel incisions 4 4 on either side of the nail incision being small and also running parallel with l the grain of the wood assists the grain in closing the greater incision to wit, the nail incision so that in a short period the grain of the wood unites and closes said nail incisions 1 so completely that it is impossible to tell where the nail has been driven after sandpapering and varnishing the surface of the wood. Having described my invention, 1 claim- 1. The herein-described method of uniting interior finish and other fine woodwork, so that the nail incisions are closed without the use of putty, said method consisting in separating the grain or fibers of the wood in the surface thereof by making an incision parallel i with the grain, in driving a nail oblong in l cross-section through said incision and countersinking the head thereof, and in applying i moisture to the wound or incision after the nail has been countersunk.

2. A method of uniting parts of interior finish and other line woodwork so that theinitial incisions for the nails will not be visible, and the use of putty in filling such incisions is obviated, said method consisting in making an incision in the surface of the wood parallel with the grain thereof, in driving a nail which is oblong in cross-section, through said incision and countersinking the head of said nail beyond the exposed surface of the wood, and in further making parallel incisions adjacent to the incision of the nail, and in subsequently applying to said incisions, moisture whereby the fiber or grain of the wood is caused to close said incisions, substantially as set forth.

3. A method of uniting parts of interior finish and other fine woodwork so that the incisions will become invisible without the use of putty said method consisting in making an oblong incision in the surface of the wood parallel with the grain thereof, in driving a nail oblong in cross-section through said incision with the greatest cross-sectional width of said nail parallel with the grain of the wood, and in counter-sinking the head of said nail below the surface of the wood, in making an oblong incision on either side of the nailincision and parallel therewith, and in applying to said incisions a liquid compound consisting of water, whiting and a pigment whereby the said incisions are caused to close and the effect of the acid in the wood coming in contact with the metallic nail is neutralized.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM J. BODA.
